Intel® Server Chassis SC5400 5U Kit TPS System Cooling

Revision: 1.0

4.5 Fan Header Connector Descriptions

All system fan headers use pulse width modulated (PWM) fans for cooling the processors in the

chassis. PWM fans have an improved RPM range (20% to 100% rated fan speed) when

compared to voltage controlled fans.

Base Chassis Fans are a 4-wire/4-pin style designed to plug into 4-pin or 6-pin SSI Fan

headers. When plugged into a 6-pin header, only the first four signals are used (Pwr, Gnd,

Tach, PWM)

LX Chassis fans are a 6-wire/6-pin style designed to plug into 6-pin headers. The extra signals

provide for fan redundancy and failure indications (Pwr, Gnd, Tach, PWM, Presence, Failure).

Server Boards installed in this chassis may feature an additional two 4-pin CPU fan headers

and two 4-pin System fan headers. These connections are not required for use with the Intel®

Server Chassis SC5400.

To assist with fan connections in the system, the system fans are numbered one through four

and color-coded. These correspond to fan header numbers on the server board. Fan 1 and fan

2 connectors are white in color and the fan 3 and fan 4 connectors are blue in color. These

colors should also match between server board and fans.
